Hi @bumble81, sorry to hear about your recent struggle with digestive issues, stomach pain and feeling like food is getting stuck. It is hard to function on a daily basis with those symptoms and going undiagnosed just gets frustrating after a while. I know because I have had similar issues and I found out that mine were caused by a perforation of my abdominal wall due to ulcers. The excessive belching can definitely be ulcer related as that could be a sign of an infection in the stomach lining. You will see @jimhd @pumpsi @sickvick @kaforester3 and @engelee discuss similar problems in this group.
Is the doctor you are currently seeing a Gastroenterologist? Have they done an endoscopy on you or put you on any medication to counteract your symptoms?
